ALright lets compare Gerorge Perez's Aquaman with Ivan Reis
Reis's (and just so no one can claim that it looks better only cus of modern coloring im just posting inks)
no compare the Art, sorry i coudnt find larger pics of perez's work
Perez's style is dated, yes. I recall picking up his issues of Brave and the Bold a few years ago and def thought it was the 1980's all over again. Back in the day when panels were boring his style was considered energetic but I have to admit trying to read him now makes reading a story a bit of a slog. I don't know if that is good or bad but using the B&B issues as an example, I can't say I enjoyed them more because of his style.
If I had to classify him I'd say he is more centered on dramatic slices and dynamics which is quite different than, say, Hitch's fluid style or Frank's realistic style. Taste's change and I can understand why people don't care for him as much as they used to but to say he isn't any good shows your ignorance. I personally can't stand Hitch and I find Frank's style kind of creepy, but they are both very talented artists in their own right.
